Tym ODP Mini 2nd hand

Based on my original DOD 250's this is my version of this great overdrive preamp from the late seventies into the early eighties. This uses original value components and the original "legendary" LM741 IC. My version has true bypass switching, an LED and a Boss style 9V input adaptor, none of which the original (or re-issue) DOD 250's had. Hand built in my new smaller stainless steel enclosures on custom designed Tym PCB's.
